Appendix A—Installing task3G

This section describes how to install task3G for your environment. Task3G is installed through the COSmanager configuration menu.

See Installing COSmanager Applications in the COSmanager User Guide for full details.

What you need

1. the COSmanager framework installed on the target platform
2. a distribution file containing the task3G software
3. a valid license key
4. you must be a COSmanager user with the Manager role

Installing task3G

1. Load the CDrom in a CD drive on the local host or a network CD drive.
2. Mount the CDrom using the appropriate mount command for your operating system (listed on the inside of the CD jacket).
3. From the Product configuration menu, select COSmanager configuration > COSmanager applications.
4. Select Application > Install.
5. Enter the name of the host to which the CD drive is attached. In Install from, enter the file name containing the product distribution. Press Accept.
6. You will see the application contained in the distribution file. Choose the row titled task3G version 4.1.
7. Enter the name of the directory where you want task3G to be installed and press Accept.

COSmanager copies the task3G files from the CD distribution file to the target directory and creates the task3G audit trail.

Appendix B—Job Recovery Action Outcomes

The following diagrams contained in this appendix illustrate the actions for each type of job recovery.

Figure 21 — Pre-condition and error recovery

In figure 21, the flow of the pre-condition and error job recoveries are illustrated. One thing to keep in mind is that depending which override status is selected (this is configured in when defining a job, see How to Define a Task on page 36.) will depend on what status the task will end in if an On-error command is defined.

Figure 22 — Kill job and timeout recovery

Figure 22 illustrates the kill and timeout job recovery actions.

Appendix C—Tutorial

The following diagram represents the relationships between the jobs and tasks that will be created and run.

Tutorial 5: Adding Tasks to a Job and Creating Dependencies

1. Highlight job1 and select Maintain > Task in job . At this point you will be presented with the Tasks in job console which contains a list of all tasks in the selected job, being job1 in this case. It's from here where you can add tasks to a job and create dependencies.
2. Select Maintain > Add to add the tasks. A list of all tasks will be presented. Select all the tasks needed for job1. These are: task1, task2, task3, task4, task5, task6 and task7.
3. When done press Accept. All the tasks now should appear in the Tasks in job console. In the current configuration all the tasks will run in parallel. Looking at the task relationships within job1 from the diagram presented at the start of this appendix, task1, task2 and task3 are not dependent on any other task and will run in parallel. All other tasks are dependent on another task.

The following steps create the dependencies for task4.

1. Highlight task4.
2. Select Dependencies > Cut.
3. Highlight task1.
4. Select Dependencies > Paste. Task4 should now appear with indentation under task1. This signifies that task4 is dependent on task1.
5. Highlight task4.
6. Select Dependencies > Link.
7. Highlight task2.
8. Select Dependencies > Paste. Task4 should now also appear with

indentation under task2. This signifies that task4 is dependent on task2. A task can only appear in a job once but dependent on multiple tasks. The first instance of a task in a job dependency structure is displayed normally, and all other instances (multiple dependencies) are represented by links.

The following steps create the dependencies for task5.

1. Highlight task5.
2. Select Dependencies > Cut.
3. Highlight task3.
4. Select Dependencies > Paste.

The following steps create the dependencies for task6.

1. Highlight task6.
2. Select Dependencies > Cut.
3. Highlight task4.
4. Select Dependencies > Paste.

The following steps create the dependencies for task7.

1. Highlight task7.
2. Select Dependencies > Cut.
3. Highlight task4.
4. Select Dependencies > Paste.
5. Highlight task7.
6. Select Dependencies > Link.
7. Highlight task5.
8. Select Dependencies > Paste.

All the dependencies have now been created.

1. Select Dependencies > Optimise to check and correct any deadlocks.

Move onto the next job.

1. Select View > Another job.
2. Highlight job2
3. A list of all jobs will be presented. Select job1.
4. When done press Accept. At this point you will be presented with the Tasks in job console which contains a list of all tasks in the selected job, being job2 in this case.

It's from here where you can add tasks to a job and create dependencies.

1. Select Maintain > Add to add the tasks. A list of all tasks will be presented.
2. Select all the tasks needed for job2. These are: task1, task5 and task8.
3. When done press Accept. All the tasks now should appear in the Tasks in job console. In the current configuration all the tasks will run in parallel. Looking at the task relationships within job2 from the diagram presented at the start of this appendix, task1 is not dependent on any other task. All other tasks are dependent on another task.

The following steps create the dependencies.

1. Highlight all tasks.
2. Select Dependencies > Sequence.
3. Select task5 and holding down the left mouse button, drag task5 to the bottom of the list. The list should be in the following order: task1, task8, task5.
4. When done press Accept. A sequence of dependent tasks should now appear.

Configure the subjob.

1. Highlight task8.
2. Select View > Subjob. At this point you will be presented with the Tasks in job console which contains a list of all tasks in the selected subjob, being subjob1 in this case. It's from here where you can add tasks to a subjob and create dependencies.
3. Select Maintain > Add to add the tasks.
4. A list of all tasks will be presented. Select all the tasks needed for subjob1. These are: task1 and task5.
5. When done press Accept. All the tasks now should appear in the Tasks in job console. In the current configuration all the tasks will run in parallel. Looking at the task relationships within subjob1 from the diagram presented at the start of this appendix, task1 and task 5 are not dependent on any other task. Therefore no dependencies need to be configured.

You have successfully populated the jobs and created the dependencies. You have successfully populated the jobs and created the dependencies.

Tutorial 6: Creating Wait Conditions

1. Highlight job2 and select Maintain > Task in job . At this point you will be presented with the Tasks in job console which contains a list of all tasks in the selected job, being job2 in this case. It's from here where you can wait conditions.
2. Select job8.
3. Select Dependencies > Wait for.
4. Enter the following for each relevant field:
5. Press Check syntax to check the syntax of the wait condition.
6. When done press Accept. The wait condition has been created.

You have successfully created a queue. Field Wait condition Wait condition $job1:task7 Timeout (mins) On failure assist
